Improvement in steering-propellers



UNITED STATES GLEMENS ULLER AND JASPER N. BENNETT, OF COLUMBUS, OHIO.

IMPROVEMENT IN ST ent No.

Specication forming part of Letters Pat March To all whom it may concern:

Be it known that I, CLEMENs ULLER and JAsPER N. BENNETT, of Columbus, in the county of Franklin and State ot' Ohio, have invented a new and Improved Apparatus for Propelling and Steering Vessels, of which the following is a specification:

In the accompanying drawing, Figure l represents a top view, Fig. 2 a vertical longitudinal section on line x :10, Fig. l, and Fig. 3 a bottom view, of our improved apparatus for propelling and steering vessels.

Similar letters of reference indicate correspondip g parts.

The object of this invention is to provide, as an auxiliary device for vessels already built, or to be built, an improved propelling 4 and steering apparatus, by which the vessel may be propelled to the right or left, forward or backward, without stopping the engine5' and the invention consists of a vertical revolving shaft, with horizontal paddles that are submerged in the water, and turned alternately into horizontal position by a cam of a sleeve around shaft, said sleeve being adjusted by a steering-lever, in connection with a disk and ratchet device.

In the drawing, A represents the stern or other part of a vessel,to which our propelling and steering device is attached. It is constructed of a vertical shaft, B, that is revolved by a crank, D, or otherwise, in one direction, in connection with the engine of the vessel. The revolving shaft B is provided at the lower end with horizontal paddles O, which extend in diametrically-opposite direction from the shaft, and submerged in the water, being supported in a bearingv of. the shaft in such a manner that they may readily turn around their axis when passing' over a cam, e, of a sleeve, E, placed around shaft B. The paddles bear against seats a of the shaft when in vertical direction.

The cam e is inclined at the ends to admit the gradual swinging of the paddles O, which are so placed by sockets on their short con.

necting-shaft that they are at right angles to each other. The paddles are concaved at the front side of the sockets, where they form contact with the inclined cam e, and so as tol swing. gradually, without jerking, from hori- EERiNG-PROPELLERS.

zontal into vertical position as they are revolved by the shaft.

When in horizontal position the paddle cuts the water without propelling, while the other paddle, being then in vertical position, exerts a forward propelling motion.

The sleeve E is guided in suitable manner to swing around the shaft, and connected by a handvlever, F, and an adjusting paw! or ratchet, or other mechanism, with the top disk G, for the purpose of employing the paildles for steering purposes.

When the lever is set in the position shown ward direction, as the cam acts on the padmotion to the vessel; but when the lever that is turned by the sleeve in a direction opposite to that of the revolving shaft is set in any other direction into the ratchet of the disk, the strokes of the paddles are produced at an angle, or in reverse direction to their former stroke, and thereby the vessel steered in reliable manner to the right or left or backward without requiring the stopping'of the engine. l

If desired, more than one set of paddles may be arranged, which are then revolved in opposite direction to the former, the steering being accomplished by one or the other, for1ning thus a reliable and effective steering and propelling device for the different classes of stea1n-vessels- Having thus described our invention, we claim as new and desire to secure by Letters Patent- An improved propelling and steering apparatus for vessels, consisting of a revolving shaft with alternately swinging horizontal paddles placed at right angles to each other, in combination with the cam of a sleeve, and adjusting-lever turning in opposite direction to the shaft to steer and propel the vessel in either direction without stopping the engine, substantially as and for the purpose herein specified.
